"It is with a heavy heart that we announce Giant George died last night. George passed away peacefully surrounded by loved ones; one month before his eighth birthday," his owners David and Christine Nasser announced on Facebook.

Measuring 3 ft., 7 in. from paw to shoulder, Guinness World Records crowned the Great Dane the Tallest Living Dog and Tallest Dog Ever back in 2010. Even though he weighed in at nearly 250 lbs., "He's just the sweetest, kindest dog, and he doesn't realize what all the hoopla is about," Guinness spokesperson Jamie Panas told PEOPLE at the time. "I was completely awestruck."

Surprisingly, George was the runt of his litter, but he quickly grew, eating 110 lbs. of dog food each month.

Added the Nassers: "We appreciate the love and support you have given Giant George over the last several years."
